Which would you rather listen to? One day of the complete works of Ravel and Webern or one month of the complete works of Telemann? Quality > Quantity. 
I agree - which is why Telemann would win handily in such a poll - quality and quantity!!

...runs for cover.... This might be a fun poll one day.
Looking at my collection, I already have more Telemann than Ravel, Webern, Janacek, and Berg combined! So I guess you know how I would vote...
